Abstract
A method and system for controlling a battery SOC of a hybrid vehicle are provided to improve fuel efficiency in an urban area with a differentiated strategy for controlling auxiliary battery SOC balance of the hybrid vehicle. The method improves fuel efficiency in urban areas with a differentiated strategy of controlling SOC balance of an auxiliary battery considering that the degree of influence of electric field load consumption on fuel efficiency based on LDC voltage adjustment in the hybrid vehicle varies based on driving mode and road gradient.
